While walking to school you pass a barn with a silo. Looking up to the top of the silo you estimate the
angle of elevation to the top of the silo to be about 14°. You continue walking and find that you were
around 40 m from the silo. Using this information and your knowledge of trigonometric ratios calculate
the height of the silo in meters.
Note: The silo is the structure beside the barn.
Ensure that you write only the number/numerical value to the nearest whole number. For example,
if you think the height is 20.1 meters, write "20".
